Application tiled December 26, 1899. Serial No. 741,645. (No model.)

T0 all wwnt it Indy concern:

Be it known thatl, JOHN J. HEYS, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Leveling-Machines,of which the following is a specification.

This invention relates to a new and improved leveling-machine; and it consists in certain novel features of construction and arrangement of parts, which will be hereinafter. fully described in the specification, clearly illustrated in the drawings, and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings, and the characters marked thereon, which form a part of this specification, in which like characters designate like parts or features wherever they occur.

Of the drawings, Figure l represents in perspective a machine embodying my invention. Fig. 2 represents a side elevation of the same. Fig. 3 represents a longitudinal sectional View ofthe machine on the line 3 3 ot' Fig. l, Fig. 4 represents a perspective view of the frame of the machine. Fig. 5 represents a detail view of the brake mechanism. Fig. 6 represents a detail view of the mechanism for tilting the jacks. Fig. 7 represents afront elevation of the upper end of the machine, showing the arrangement of the gearing and the movable members with relation to the stationary cam. Fig. S represents a top plan view of the upper end of the framework, showing the arrangement of the antifriction-rollers carried by the movable mold members.

Referring to the drawings, in the embodi-I ment of my invention therein shown and selected by me for the purpose of illustration, a represents the standard of the machine. (See Fig. 4:.) This standard is composed of front legs d', rear legs a2, and suitable connecting-bars d3. The rear legs a2 are longer than the front legs ce', thus holding the framework and mechanism of the machine in a tilted position, as distinguished from either a vertical or a horizontal position.

l) represents a shaft mounted in suitable bearings in the standards at the rear end of the machine. b represents a wheel loosely mounted upon said shaft and adapted to be driven from any source of power. h2 represents a clutch mechanism splinedV upon said shaft in the usual way arid adapted to be con= nected to and disconnected from the wheel b in order to start and drive the 'machine or stop it.

c represents a treadle-lever, here shown as a bell-crank pivoted at its angle to a bracket c' at the rear of the machine. A footpiece c3 is formed upon the end of the long arm of the lever.

c4 represents a lever pivoted midway between its ends upon the. front bar 0.3 of the standard. The lower end of this lever is provided with a roller c5 and the upper end with a roller c6. The roller c6, as shown, is an eocentric secured to the end of the lever c4 by a screw 0X. By adjusting the eccentric the time when the eccentric is engaged by the jack to trip the lever c4 can be varied at will.

c7 is a spring connected at one end with the lever c4 and at its other end to one of the legs ct in such a way that the spring normally tends to draw the roller c5 onto the top of the lever c when the latter is depressed.

o8 represents a short rod mounted in lugs e9 upon one side of the lever c, close to the footpiece c3.

010 is a linger fast upon the inner end of the shaft cs in a position to engage the lower end of the lever c1 when it is moved toward said lever by the rocking of the shaft cs. This movement of the shaft cs is effected by means of a footpiecec, fast upon the outer end of the shaft CS, in close proximity to the footpiece c3. When the lever c is depressed to start the machine, as hereinafter described, the spring cT draws the roller c5 upon the top of the leverc. Bythis means the lever c is held depressed until the rollr cG is engaged by one of the jacks, when the roller cG is carried to the rightin Fig. 1, thereby withdrawing the roller c5 from the lever c, permitting said lever to be lifted and the power thrown off the shaft ZJ. If for anyreason it is desired to stop the machine after it has once started before the lever cL is tripped automatically, as described, the operator by depressing the footpiece c11 can force the iinger 010 against the rod cl to trip the same and permit the treadle to rise. Should the operator desire to control the movement ofthe machine as a shoe is going into pressure or otherwise, he can by simultaneously depress- ICO ing the pieces c3 and c start the machine, prevent the roller c5 from engaging the top of the lever c, and thus stop the machine at any desired point by removing his foot from the pieces c8 and ou.

c12 is a spring connected at one end to the short arm of the lever c and at the other end to the standard a? at the rear of the machine in such a Way as to normally tend to throw the front end of the lever c or the footpiece c3 upward and to maintain it in its raised position or the position it occupies when the clutch b2 is disconnected.

b3 represents a bell-crank pivoted at its angle to the rear end of the standard of the machine. One arm of this bellcrank is formed as a fork b4 and is connected by a pin b5 to the sliding member of the clutch b2 in the usual manner. The other arm of this lever is connected by a pitman h6 to the end of the short arm of the bell-crank c.

E7 represents a Wheel fast upon the shaft b on'the opposite side of the machine from the wheel b.

bs represents a brake strap one end of which is secured to the standard of the machine by a screw b9. This strap passes around the wheel hl, as shown, and its free end is formed with a linger bw.

Z111 represents a lever pivoted midway of its ends upon the standard at the rear of the machine, but on the same side of the machine as the pulley 67. At one end of this lever is formed a pair of lugs Z712, which loosely embrace the free end of the long arm of the bellcrank b3. formed with a finger 1913, arranged to engage the finger-b10 of the brake-strap. vThis brakestrap is composed of a metal ring fitting snugly to the wheel 1)? about the entire periphery of the latter and when moved by the finger b13 acts as a part of the grip.

From the described construction it will be seen that when the lever c is depressed by means of the pitman and the bell-crank b3 the clutch b2 will be thrown into engagement with the power-wheel' b". This movement of the treadle also throws the nger Z113 away from the iinger blo of the brake-strap, thereby loosening lthe latter. Vhen the treadle c3 is raised by the spring cl2, the operations just described are reversed-that is, the clutch h2 is disengaged from the wheel b and the finger Z913 is thrown into engagement with the linger blo to tighten the brake-strap on the pulley 197 and stop the motion of the machine.

frepresents a shaft mounted in suitable bearingsf,connected to the standard at either end of the machine.

f11 represents a worm-gear fast upon the shaft at the rear end of the machine and arranged to mesh with and be driven by a worm p Z214 upon the shaft b.

f2f2f2f2 represent rods bolted at one end to the gear f and at their other ends secured to a disk f3, fast upon the shaftf at the front of the machine. These rodsf2, as shown, run

f4 represents a stationary path-cam at the front of the machine. l

f5 represents a stationary cam at the rear end of the machine, immediately adjacent and in front of the Work-gear fu. The cam f5 is suitably supported by parts f6, secured to said cam and to the standard of the machine. The carnf5 has its high part, by which the presses are shut, underneath the machine,

and its low or neutral point, where the presses are opened, at the top of the machine. (See Fig. 4.)

f7 represents a cam arranged on top of theV Y machine. (See Figs. 2, 3, and 7.) This cam is supported by arms f8, extending from the cam f5 on opposite sides of its neutral point,

near the top of the machine. (See Fig. 7.)

It will thus be seen that the Y Y 5 presses go into pressure gradually as they go under the machine and that the presses are open as they come to the top'of the machine, the cam f5 serving to shut the presses and the cam f7 serving to open the presses. The Vgear f11 is provided with a plurality of pairs of lugs f221 to receive pins fm, upon which are journaled rollers fm, which bear directly against the cam.

h represents a guide-plate, formed with a IOCV hub h', secured to the shaft f immediately be-Y low the cam plate are formed-four sockets h2. these sockets is arranged a cylinder h3. This cylinder at its upper end is formed with a pair of ears h4, adapted to hold a pintle h5, upon which is mounted a roller h6 between said ears.

h3 is a stop secured to the pintle by a setscrew hf, which serves to limit the downward movement ot the cylinder 72,3 by engagement with the disk h. The roller h6 is arranged to be engaged by the path-cam f5, being depressed by the upper part of said cam and raised by Ithe lower part of said cam. The rollers 71.6 and f21 are directly opposite each other, as shown in Fig. 3.

T5 represents a rod secured at its upper end to the base of the cylinder 71,3. This rod r represents a spring arranged in said 13oVV upper end of the cylinderand atits other end passes down through an opening in the handwheel?1L and into a chamber formed at the lower part of said hand-wheel and in the mold-carrier. This rod has on its lower end a retaining-nut r6 and a check-nut r1.

fr8 represents a mold connected to a sliding plate r9, adjustably secured to the mold-carrier r. A screwrmpasses through said plate and engages the carrier r. By means of this screw the sliding plate r9 and its mold can be adjusted. r11 represents a latch arranged to engage the screw T10 and hold the plate in its adjusted position. The moldcarrier r is formed upon either side with a guide T12, which engages and slides upon two contiguous rods f2. The mold-carrier is therefore guided by the sockets h2 and the guides T12, and the hand-wheel is in a convenient position for adjusting the mold carrier. As shown in the drawings, there are four of these reciprocating molds 11B and connected mechanism; but as these structures are identical a description of one will suffice for all.

s represents a jack-table pivoted at s' to the dislrf3 between two of the rods f2, there being a jack-table for each corresponding mold-carrier rr.

s2 represents a jack or last constituting the lower mold member, mounted upon the jacktable s. As here shown, a pin s3 extends from the table s into the jack. In order to retain the jack in place on the table, I secure to the table s a pin s4, which carries a block S5. In this block a sliding pin s6 is mounted. This pin s is adjustably locked in place by a grip 37, operated by a lever S8. W'hen it is desired to substitute one form of last or jack for another, the grip S7 is loosened, the pin s6 removed, and the jack or last taken off the table and another one put in its place, after which the pin s is pushed forward into the jack or last and locked.

t represents a sleeve arranged to slide upon one of the rods f2. t is a pitman pivoted at one end to said sleeve and at its other end to a lug t3 on the bottom rear portion of the pivoted jack-table s.

t4 represents a pitman pivoted at one end to the lower part of the sleeve d and carrying at its lower end a roller t5, loosely arranged in the groove of the path-cam f4. As the machine revolves the jack-tables remain in the position shown to the right in Fig. 3, except when the rollers on the pitman t4 reach the inclinemof the path-cam. This incline forces up the pitman t1 and the sleeve t, causing the jack-table and its jack to be tilted, as shown, to the left, in Fig. 3. Each of the jack-tables is connected up to the path-cam f1 in a like manner, so thata description of one will suffice for all. By reason of the loose connection between the rollers t5 and the path-cam f1 the jack is given sufficient play to enable it to automatically position itself in engagement with its complemental mold and to prevent breaking the pitman t4, which might occur if the jack were tilted slightly by the mold and the connection between the lroller 't5 and the path-cam f1 were so light or so close as not to admit of the described play. I do not coniine myself to the particular means for effecting this described play.

The operation of the machine is as follows: A shoe having been placed upon the jack or last s2, the lever c is depressed andthe machine started. The rotation of the machine will irst throw the jack, that was in a tilted position or the position shown in Figs. 2, 3, and 6, back into position for pressure, or the position shown at the right in Fig. 3. Immediately thereafter the cam f5 yieldingly forces down the mold rs upon the sole of the shoe. After this takes place and before the first mold has reached the limit of its throw its jack trips the lever c4, stopping the machine. While the shoe just described is going into pressure the shoe upon the succeeding jack is being withdrawn from pressure, the mold being drawn up by the path-cam f5. The shoe is not put under full pressure at the first operation. Before the roller h6 of the mold that is moving out of pressure reaches the height of the incline on the cam fs the jack having the shoe that is going into pressure trips the lever c4 and automatically stops the machine. At this time the mold of the succeeding press has been drawn up to the limit of its movement, and just as the machine stops the roller on the pitman t4 on the succeeding jack-table is engaged by the incline of the path-cam f4, thus automatically tilting the succeeding jack and its shoe out of the machine in a position where the shoe can be removed from the jack and another shoe placed thereon. The operation just described is repeated for the remaining jacks.

It will be noted that the machine stands in an inclined position, (see Fig. 2,) so that but a small motion is required to be given to the jack, about thirty-ive degrees, in order to throw the sole of the shoe out of the machine and in a horizontal position. This arrangement of the machine is of great advantage, since the whole mechanism of the machine is practically removed from the vicinity of the operator and the jack is thrown out of the machine in a position where the necessary manipulation of the shoe can be made by the operator unhampered by the other mechanism of the machine. Further, the framework of the machine and the mechanism carried thereby are inclined and rotate, 'and the operator can watch the shoes as they go into pressure on one side and as they come out of pressure on the other side of the machine, thus being enabled to determine if the shoe IOO TIO

is properly positioned for pressure before the Y full pressure is applied at the second operation and to determine if the shoe has been sufliciently pressed before starting the mamachine and the other side as it comes out. The vmotion of pressure to be given the sole can thus be regulated by the operator, since he has a chance t0 see the action of the press on the shoe before final pressure is put on, and if this is going to be too great or too little he can correct this by turning the handwheel r2 before again starting the machine. Another advantage of the described arrangement of mechanism is that it is practically impossible for the operator to be injured, as frequently happens with the upright class of the machine. v

By referring to Figs. 1 and 2, it will be seen that the only press that comes toward the operator is one that is opening. Further, the press that is coming is the one requiring the operators attention, the other closing press having been loaded and moving away in its simultaneously closing action. After the machine is started the operator immediately turns his attention to the jack that is approaching him from beneath the machine, and in practical working the operator has removed the shoe by the time the jack has reached its position of rest, as shown in Fig. 6.

Having thus explained the nature of my invention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, what I claim, and desire to secure by Letters Patent, is-
